has_many :through associations give different results depending on eager-loading via :include

Reported by David Lee | April 7th, 2009 @ 11:40 PM | in 3.x

class User
  has_many :comments
  has_many :posts, :through => :comments

class Comment
  belongs_to :user
  belongs_to :post

x = User.create
x.comments.create :post_id => nil

x.posts #=> []

x = User.find :first

x.posts #=> []

x = User.find :first, :include => [:posts]
x.posts #=> [nil] !!!

I'm not sure if posts should return [] or [nil], but the result should be consistent regardless of whether the association was eager-loaded or not.
